Be it known that I, AUGUST Nlrnivnnin'a citizen of the Republic ofFinland, residing at Detroit,in the county of Wayne andV State ofMichigan, have invented new and useful improvements in Scribing Tools,of which the following is a specification.

This invention relatesto tools used in the metal and wood-working tradesfor scratching or scoring lines on the material to aocurately locate theplaces where the same is to be cut, and the invention has for vitsobject to provide a very simple and eicient tool of this kind, the sameconsisting of a novel combination and arrangement of parts to behereinafter described and claimed.

In order that the invention may be better Y understood, reference is hadto the accompanying drawing, wherein-- Figure 1 is a plan view of thetool;

Figs. 2 and 8 are side'elevations illustrating two different ways ofusing the tool, and

Fig. 1 is a sideelevation of a modification.

Referring specifically to the drawing, and more particularly to Figs. 1to 3, the reference numeral 10 denotes a scale blade having at one ofits ends an upstanding flange 11 which may be formed by a right-angledbend in the blade. The scalegraduations are on that side ofthe bladefrom which the iiange projects. A short distance from the iiange 11, andon the sameA side of the blade 10 as said flange, the blade carries apost 12 having a transverse aperture in which is slidably mounted agraduated scriber rodI 13. A set screw 14, threaded Yinto the post toengage the scriber rod is employed for holding the latterV in adjustedposition.

The scriber rod 13 projects from opposite sides of the post 12 sothatoneend may lie above the graduated side of the blade 10, whereas its otherend passes loosely through an aperture in the flange 11. Each end of theseriber rod has a scribing point, the same being denoted by thereference numerals 15 and 16, respectively. Both scribing points may belateral bends at the ends of the rod, said bends having sharpened orpointed extremities.

The scribing point 15 1s used principally in automobile body and othersheet metal work where the sheet metal is to Vproject a certain distancefrom the edge of the wood so that it may be bent over the same. 1n usingthe tool `tor this work, the scriber rod 13 is slid until the point 15is opposite the graduation oii the blade 10 which denotes the desireddistance thel metal is to project from the edge of the wood. The rod islocked in adjusted position by the set screw 14. The point 15 being nowlocated inwardly of the end of the blade, the tool is placed so that theprojecting piece of metal comes between the point and the opposite sideof the blade 10, and the latter is then advanced until. theaforementioned end thereof comes in Contact with the edge of the wood,as shown in Fig. 2. It will be understood that the scribcr point isspaced from the scale blade a suticient distance to permit the sheetmetal to be marked to come therebetween. Now, with the edge of the woodguiding the blade 10 l the latter is drawn along said edge so that thescriber point 15 may scratch a line on the metal. A slight pressure onthe rod 13 in a direction to bring the scribe-r point in contact withthe metal to be marked suffices to scratch the line on the same..

As shown in Fig. 3, the scriber point 16 may be used for scratching aline a certain distance from the edge of a piece of wood, the rod 13being set to leave the point projecting this distance from the fiangell,and the latter being placed against the edge of the work to guide thetool. The scale on the rod 13 is used `for this setting of the scriberpoint 16.

Fig. 4 shows a slight modication. Here, instead of the scriber point 16,a rotatable scriber wheel 17 is provided.

I claim:

1. A scribing tool comprising a scale blade having one side graduated, apost on the graduated side thereof, and a longitudinally adjustable rodcarried by the post and eX- tending parallel tothe blade, said rodhaving a scriberv point positioned opposite and spaced from thegraduated side of the scale blade.

2. A scribing tool comprising a scale blade having one side graduated, apost on the graduated side thereof, and a longitudinally adjustable rodcarried by the post and extending parallel to the blade, said rod havinga lateral end bend in the direction of the graduated side of the scaleblade, with its extremity pointed and spaced from sai side.

3. A scribing tool comprising a scale blade having one side'graduatedandhaving an Vapertured later-al flange lat one end, a post apertuiledlateral flange at Vone end, .a'post onv the'graduatecl'sidevof 4saidblade, and a Y on the graduated sideV of said blade, and alongitudinally adjustableV and graduated longitudinally adjustable rodcarried by the rod carried by the postrparallel to the blade,
